Re: saki also = Japanese for happiness

Yes, thank you -- the restaurant's website shows 幸 as part of its logo, which my dictionary glosses as "happiness; blessing; fortune".

(Though my dictionary notes "saki" as a reading of that character only in the "only in proper names" section, which probably explains why I didn't find it at first. The regular readings it gave are "kou; saiwai; sachi; shiawase".)
